Jeffkad,
I have the K-01 and agree that the sound of the K series is indeed very neutral. If you are looking for a warmish sound, you can still get the K-03 but add a tubed pre-amp. A very good tubed pre-amp to consider is the ARC Ref 5SE. I used to own the Ref 3 and am now considering the Jeff Rowland Corus and Ref 5SE. I am waiting for a home audition of these 2 pre-amps before making a decision but currently am unable to get hold of well broken-in units for audition.
